DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 268,670, dated. December 5, 1882.

` Application filed April 13, 1882. (No model.)

To all whom it may concern:

Be it known that I, DANIEL Pfl-IERSIIBEEn GER, of Goshen, in the county ot' Elkhart and btate of Indiana, have invented new and uset'ul Improvements in Draft-Equalizers; and I hereby declare thatthe tollowingisafulhclear, and exact description thereof, reference being had to the accompanying drawing, which form 4a part of this specification.

The nature ot' this invention relates to certain new and useful improvements in the construction of three-horse equalizers.

The invention consists in the peculiar construction, arrangement, and various combinations ofthe parts, all as n'ore fully hereinafter set forth.

In the accompanying drawing, in which my invention is shown in perspective- A represents the ordinary two-horse evener, provided with a suitable clevis or other means at its longitudinal center with which to attach it to the articlevto be drawn. To each end ot this evener, and upon the top thereof, I Ipivotally secure the clips a by means ot' a proper bolt. Between the ears of these clips l pivotally secure the double-trees B, at one side of their longitudinal center, and with the longer arm projecting inwardly. To the inner or `longer arms ot these double-trees B, I secure in any convenient manner the single-trees G, `while to the shorter or outer arms l attach the `,cured to the evener A by a bent loop, c, and

two bolts passi-n gat rightangles to each other- 4o one through each end of the loop c. By this construction I provide for an up-and-down or vertical play otl the double-trees B, which reieves the central horse from `the downdraft, which occurs especially in plowing.

What I claim as my invention is v1. Adraft-equalizer wherein the double-trees B are pivotally secured to the upper face ofthe main evener, and adapted to have a vertical rocking movement, substantially as and for the purposes set forth.

2. In a. draft-equalizer, the combination, with the evener A and the double-trees B, ot the loops c and vertical and horizontal pivot-bolts passing through the evener and double-tree at 5,5 right angles to each other, substantially as described, and for the purpose specied.
